3M™ GLASS BUBBLES S28HS
Glass Bubbles S28HS are hollow glass spheres with a typical density of 0.28 g/cc and an isostatic crush strength of 3,000 psi. These glass bubbles are designed for numerous applications such as deep water syntactic foams and airless spray coatings. The bubbles produce strong, stable voids with low thermal conductivity, helping the coating achieve the necessary compressive strength. The S28HS Glass Bubbles offer a very good strength-to-density ratio and small particle size, making them suitable for a variety of applications such as buoyancy in oil and gas, airless sprayable paints and coatings, adhesives, mastics, sealants, SMC and other thermoset resin systems.
